System and method for adjusting number of advertisement inventories

Abstract

Provided is a system and method for adjusting a number of advertisement inventories based on a competition factor. An advertisement inventory adjusting system includes a competition determining unit to determine a competition factor for a keyword, an advertisement inventory adjusting unit to dynamically adjust the number of advertisement inventories based on the determined competition factor, and a data storage medium to store advertisement inventories. A method that uses a processor to adjust a number of advertisement inventories includes determining a competition factor for a keyword advertisement with respect to a keyword, and dynamically adjusting, using the processor, the number of advertisement inventories based on the determined competition factor, in which the advertisement inventories refer to available areas to display the keyword advertisement.

1 . A method that uses a processor to adjust a number of advertisement inventories, the method comprising:
 determining a competition factor for a keyword advertisement with respect to a keyword; and   dynamically adjusting, using the processor, the number of advertisement inventories based on the determined competition factor, wherein the advertisement inventories refer to available areas to display the keyword advertisement.   
     
     
         2 . The method of  claim 1 , wherein the determining a competition factor for a keyword advertisement comprises:
 determining the number of advertisement inventories with respect to the keyword;   determining a number of valid advertisements with an advertising performance exceeding a reference threshold with respect to the keyword; and   determining the competition factor for the keyword advertisement based on the number of advertisement inventories and a number of valid advertisements.   
     
     
         3 . The method of  claim 2 , wherein the advertising performance is measured in amount of valid sales through the keyword advertisement, and valid advertisements refers to a keyword advertisement of an advertiser for the advertisement inventory. 
     
     
         4 . The method of  claim 1 , wherein the determining a competition factor for a keyword advertisement comprises:
 determining a number of registered advertisements that are registered with respect to the keyword;   determining a number of valid advertisements exhibiting an advertising performance that exceeds a reference threshold with respect to the keyword; and   determining the competition factor for the keyword advertisement based on the number of registered advertisements and the number of valid advertisements.   
     
     
         5 . The method of  claim 1 , wherein dynamically adjusting the number of advertisement inventories comprises increasing the number of advertisement inventories as the competition factor for the keyword advertisement increases. 
     
     
         6 . The method of  claim 1 , wherein the keyword advertisement further comprising charging for the keyword advertisement, wherein a charge is adjusted based on a ranking of the keyword advertisement. 
     
     
         7 . A method that uses a processor to adjust a number of advertisement inventories, the method comprising:
 determining a number of advertisement inventories with respect to a keyword;   determining a number of valid advertisements with respect to the keyword; and   determining, using the processor, whether a keyword advertisement competition has occurred based on the number of advertisement inventories and the number of valid advertisements.   
     
     
         8 . The method of  claim 7 , wherein the valid advertisements refers to a keyword advertisement of an advertiser for the advertisement inventory. 
     
     
         9 . The method of  claim 7 , wherein the keyword advertisement competition is determined to have occurred in response to the number of advertisement inventories being determined to be less than the number of valid advertisements. 
     
     
         10 . A system to adjust a number of advertisement inventories, the system comprising:
 a competition determining unit to determine a competition factor for a keyword;   an advertisement inventory adjusting unit to dynamically adjust the number of advertisement inventories based on the determined competition factor; and   a data storage medium to store advertisement inventories, wherein the advertisement inventories refer to available areas to display a keyword advertisement associated with the keyword.   
     
     
         11 . The system of  claim 10 , wherein the competition determining unit comprises:
 an advertisement inventory extracting unit to determine the number of advertisement inventories with respect to the keyword;   a valid advertisement extracting unit to determine a number of valid advertisements with an advertising performance exceeding a reference threshold with respect to the keyword; and   a determining unit to determine the competition factor for the keyword advertisement based on the number of advertisement inventories and the number of valid advertisements.   
     
     
         12 . The system of  claim 11 , wherein the advertising performance is measured in amount of valid sales through the keyword advertisement, and valid advertisements refers to a keyword advertisement of an advertiser for the advertisement inventory. 
     
     
         13 . The system of  claim 10 , wherein the competition determining unit comprises:
 a registered advertisement extracting unit to determine a number of registered advertisements that are registered with respect to the keyword;   a valid advertisement extracting unit to determine a number of valid advertisements exhibiting an advertising performance that exceeds a reference threshold with respect to the keyword; and   a determining unit to determine the competition factor for the keyword advertisement based on the number of registered advertisements and the number of valid advertisements.   
     
     
         14 . The system of  claim 10 , wherein the advertisement inventory adjusting unit increases the number of advertisement inventories as the competition factor for the keyword advertisement increases. 
     
     
         15 . The system of  claim 10 , wherein the keyword advertisement further comprising charging for the keyword advertisement, wherein a charge is adjusted based on a ranking of the keyword advertisement. 
     
     
         16 . A system to adjust a number of advertisement inventories, the system comprising:
 a data storage medium to store advertisement inventories and valid advertisements;   an advertisement inventory extracting unit to determine the number of advertisement inventories with respect to a keyword;   a valid advertisement extracting unit to determine a number of valid advertisements with respect to the keyword; and   a determining unit to determine whether a keyword advertisement competition has occurred based on the number of advertisement inventories and the number of valid advertisements.   
     
     
         17 . The system of  claim 16 , wherein the determining unit determines that the keyword advertisement competition has occurred in response to the number of advertisement inventories being determined to be less than the number of valid advertisements. 
     
     
         18 . A non-transitory computer-readable medium comprising a program for instructing a computer to perform the method of  claim 1 . 
     
     
         19 . A non-transitory computer-readable medium comprising a program for instructing a computer to perform the method of  claim 7 .
